To all whom it may concern:

Be it known that. I, HARRY E. Pnorson, a citizen of the United States, residing at llainville, in the county of Hartford and State of Connecticut, have invented certain -3 is a front end elevational view of the same. Fig. 4 is a rear end elevational view of the same. Fig. 5 is a plan view of the same. Fig. 6 is a sectional view on the line w w of Fig. 5. Fig. 7 is a similar view of the same section as viewed from the side opposite to that shown in Fig. 6. Fig. 8 is a sectional view r "be line 3 1/ of Fig. 5 on a further enlarged scale. Fig. 9 is a sectional view on the line 2 2 of Fig. 8. Fig. 10 is a sectional view on the line '0 o of Fig. 8. Fig. 11 is a. side elevation showing the punch and other adjacent parts shown in Fig. 8, on a further enlarged scale. Fig. 12 is a view in part section and in part side elevation of certain parts shown in Fig. 2, 0n the same scale as Fig. 11.

A is the base of my machine and comprises a generally rectangular, llat, horizontal plate supported at. a convenient height from the floor by means of four corner legs 25. A pair of standards extending upward from the said base A operatively support the main driving shaft B which carries the driving wheel 27 and which is driven by the belt 28, the location of the said standards 26 being intermediate the ends of the said base A and the said standards are provided with punch operating mechanism to be described. At the for ward end of the said base A are provided a second set of upright. standards 29 which have means to be described, for operating the master sheet C and there is also at the said forward end an extension in the form of side brackets 30 which support suitable product feeding mechanism 1) for feeding the paper sheet or sheets E which has been operated on and suitably perf0- rated by the punches to. be described. As shown the said'product feeding mechanism 1 comprises'a pair of endless chain belts 31 which carry each a set of cross strips 32, which latter meet as the said chains move along in synchronism and grip the perforated sheet E, carrying the same along, the said sheet being pulled over the entire length of the said base A and delivered at the front end of the said feeding mechanism 1). The operation of the feeding mechanism D is in termittent and is eii'ected by ratchet mechanlsm F that is operated by lever arm 33 and link 34, which latter is given a reciprocal motion by the eccentric connection of the same to the counter shaft G and which counter shaft is turned by the gear 36 which is mounted thereon and meshes with the gear on the said main shaft B. A third gear 37 on a second counter shaft H and meshing with the gear 36 provides a corresponding reciprocal motion to a link 38 by means of ratchet mecl'ianism I and which. serves to give a movei'nent to the said master sheet C corresponding to the movement of the said perforated product sheet E. A shaft 39 in termittently operated by the said master ratchet mechanism I carries a friction rolllt), and by means of a coiiperating friction roll 1-1 serves to feed the said i'naster The said COtil'itllittlllg friction roll 41 is supported by its ends by a pair of swinging arms 42, pivotally mounted on the said standards 29 and held resiliently in contact with the said driving roll 40, or the master C interposed between the same, by means of springs 43. The initial position of the said master C is on the roll 44 which is mounted at, the upper ends of the said standards 29 and. the same passes over a contact roll J, being suitably guided bya guide roll 64 and passes from the said contact roll to the said feeding friction rolls .nd l1 and from these is delivere to the receiving roll 45 which is operate in an ordinary man her to take up\. the master sheet U as it is delivered from the said feeding friction rolls 40 and 4:], the operation of the said receiving roll 45 shown being by means of a belt wheel 77 mounted on the same shaft as one of the sprocket wheels 54 carrying one of the endless chains 31 of the said product feeding mechanism D. The said cont-act roll J is normally stationary and serves as a friction guide for the master sheet C and is provided on the face directed generally toward the punches with a longitudinally extending contact strip K which may be insulated from the said contact roll J, and the said strip is in the electrical circuit of the selector mechanism to be described.

The said-selector mechanism comprises a pair of swinging arms 47, pivotally mounted by their lower ends to the said base A and extending upward therefrom, which are cross connected at their upper ends by a selector guide piece or block L, which is of insulating material. A spring M tends to swing the said arms 47 so as to bring the said selector 'guide block L toward the said contact roll J and the extent of such movement is limited by an adjustable stop N in abutment with a rigid cooperating stop such as the arm 48 on one of the said uprights 29. Normally the said selector guide block L is held away from the said contact roll by a link 49, which link is operated reciprocally in an ordinary manner, as by means of a pin 50, which pin is eccentrically located at the end of the said counter shaft G, and

to which pin one end of the said link is op eratively connected. The other end of the said link 49 is provided with a sliding connection with one of the said swinging arms 47 comprising a longitudinal slot 51. in the said link and a pin 52 fixed in the said arm 47 fitting the said slot 51, the relation of the said slot and pin being such that they are normally in engagement so as to hold the said selector guide block L away from the said contact roll J as described, and will permit the same to be held in a definite p0- sition relatively to the said guide roll, determined by the said stop N and its coacting arm 48 ,during an appreciable angular movement of the said counter shaft G, and

- during which movement the said pin 52 travels lon itudinally in the said slot 51. The said so ector guide block L comprises a set of holes 0 for selector ins P and between adjacent holes a' sprlng or peg 53 of insulating material, Each Y of. the said pins P comprises a straight iece of wire which is a fit for the said ho e O and suitable for longitudinal movement therein, and is of such length as to pass through the said selector guide block L so that one end will project toward the said contact roll J and the other end on the other side of the said block will receive a spring Q, to one end of which it is secured. The other end of the said spring Q is secured to the said block L. The said spring serves to resiliently 'hold the said contact pin P reguide plug siliently in the direction of the said contact roll J and is also, in each case, electrically connected so as to provide an individual or selector circuit for each of the said selector pins P. Accordingly, each pin P serves as a means for closing an electric circuit when bro-u ht into contact with the said contact roll Each .of the said pins P is headed so as to limit the forward movement of the same due to the action of the said contact pin springs Q. The said main shaft B is provided with a pair of eccentrics 55 to which are connected a pair of plates 56' hammer surface 57 suitable for operating the punches by a hammer blow. A punch lifting bar S 1s supported from the said platen below the said hammer surface 57 and has tl-IttlPIOCfll motion corresponding to that of the said platen R. Between the said lifting bar S and the base A-there is a die plate T directly on the'said base and a stripping block U immediately above the same and separated therefrom by a space 58 suitable for admitting the sheet E to be perforated.

The punch V comprises a straight piece of wire and is provided with an upward extension \V of similar wire to .which it is flexibly connected by means of a spring X. Theupper end 59 of the said extension W is normally held away from contact position with the said hammer sprface' 7 by means of a spring Y and the same is brought into contact position and in direct alingpment with l the said punch V by means of an electro magnet Z when the same is energized by the closing of the electric circuit for the windingo t said contact roll J. A bar 60 limits the lateral motion of the said upper end 59 of the extension W. 1

As shown in Fig. 8 an extension IV of one of t e punches V has its upper end in alinemen with the punch V and directly under the said hammer surface 57 and accordingly in position to force the punch downward through the paper to be perforated, being guided by holes fitting the punch in the lift mg bar S and the stripping block U, and another extension W is shown having its upper end clear of the said hammer surface 57 and beyond the edge 61 of the same, which is the normal position ,and in which it is held by the action of the spring Y. Theextensions are brought to the operating pohe same by the contact made by the corresponding selector pin P with the,

sition in opposition to the said spring Y the closing of the proper electric circuit in the manner described by means of a link 2 which is operatively connected to the am ature 63 of the said electromagnet Z, and to the said upper end. The said link 62 and spring Y serve to osition the upper/ end of the extension laterally. The said punches V are provided near their upper ends with transversely extendin lugs. or pins 65, which engage with the llfting bar whereby the punch is raised to normal position after having been operated to make a perforation in the paper. There are as many punches V as notes to be desired in the perforated sheet, and there is an electromagnet and selector finger corresponding to each punch. The lifting bar and strip-. ping plate each have holes fitting the punches, as also the die plate.

In operation, the master and the paper sheet to be perforated are intermittently fed along and brought to rest, and while in the latter condition the selector fingers are moved to the position for making contact vwith the contact block and moved away from the same. When in the contact position, with paper of the body of the master interposed between the selector finger and the contact roll there is no closing of an electric circuit and consequently no operation of the punch. In case however the lector finger is in line with a perforation in the master electrical contact is made which serves through the corresponding electromagnet to bring the corresponding punch into action and reproduce the notc'of the master in the copy. After the punch has done its work it is lifted to normal position by the lifting bar. The selector fingers are arranged in alinement, and are as described arranged to permit of contact with the contact roll for an appreciable'interval of time, and the direction of the movement of the selector fingers is essentially rectilinear.
